DefinitionAR (Augmented Reality) is technology that overlays computer-generated information on reality, such as a camera feed or the scene in front of you.
ExplanationThrough a smartphone screen or see-through glasses, digital information is added while the real scene stays in view. The overlay is not limited to flat items like text or arrows and can also be a 3D image. Examples include navigation that draws direction arrows over the road seen by the camera, and work support that displays inspection steps on top of a machine.
AnalogyIt is like laying a clear sheet over a printed map and drawing marks and routes only on the sheet. The map itself stays visible underneath.
Memory hook"Augment" means to increase or add to. AR adds on top of reality without erasing it.
